第一磨牙缺失的牙周组织变化在经典著作中认为:两侧邻牙向缺牙间隙倾斜或移位,对合牙伸长、牙松动、牙周袋形成及嘴嚼功能降低。但这些观察仅以临床经验为基础而缺乏实验证明,缺乏牙周和咬合长期变化的报告。因此,本文将我院就诊病人中第一磨牙缺失的病例作随机抽样进行统计学分析,来观察第一磨牙缺失对牙列和牙周组织的影响,从而探讨个别牙缺失后修复的实际意义。 1 临床资料:上颌或下颌第一磨牙缺失的病人13例,年龄17～60岁,均系汉族人。
Periodontal changes in the absence of the first molar In the classic book, it is thought that the adjacent teeth on both sides are inclined or displaced to the missing tooth gap, which has the effect on the extension of the tooth joint, the loose tooth, the periodontal pocket formation and the chewing function. However, these observations are based on clinical experience and lack of experimental evidence of lack of periodontal and bite long-term changes in the report. Therefore, in this paper, the cases of the first molars missing in our hospital were randomly sampled for statistical analysis to observe the effect of the first molars loss on the dentition and periodontal tissues, so as to explore the practical significance of the repair after the individual tooth loss. 1 clinical data: the first maxillary or mandibular first molar missing patients 13 cases, aged 17 to 60 years old, are Han Chinese.
